Firstly if you have another power lead check that. If that gives the same then read on.

When it comes to laptop power supplies it's easier and more cost effective to replace them.

The parts inside are dangerous, packed in very close to each other and hard to fault find the entire fault. Half the time fixing one fault, you can miss another that is buried under other components.

Try and find an ex-government/ex-lease computer seller etc in your area. They will have another adaptor second hand, or even use things like eBay etc. Just be sure to get things from good sellers, and make sure they are in your country.

If you go back to HP (they own Compaq now) you will be charged an arm and a leg for a new charger.

I bot a hp mini laptop recently.. ws working well..bt sddnly it ws nt chrgng ystrday and showed cross sign over battery in control panel.. why is it nt chrgn and wht to do?


If the laptop is still working when it is plugged in , then the ac adapter is good and the battery is just bad. If the laptop will not work when it is plugged in then more than likely the ac adapter is bad.

Hello,

Either 1) Your AC adapter needs to be reset or 2) Your AC Adapter is bad.

Most power issues with the Wii can be fixed by resetting the AC adapter. You can easily reset the AC adapter by following these steps:
Unplug the Wii AC adapter at both ends (from the back of the Wii system and from the wall outlet or power strip).

The AC adapter must remain unplugged at both ends for a full 2 minutes.

After you've waited 2 minutes, plug the AC adapter into the Wii system and directly into a wall outlet, not a surge protector or power strip. If the power light comes on and stays on, then it appears resetting the AC Adapter worked.

If it's not working, you can get a *new* NINTENDO brand AC adapter at the following

My dell vostro 1000 laptop's display aint working. The screen remains black. Even the battery light doesnt glows. Only the power light comes on. Please help.


hi,
try these two things if both don't work you should call dell tech support

1) take out the battery and the ac adapter and then push and hold down the power button for 15 seconds, this releases flea power in the laptop and makes it work sometimes
if it didn't work

2) take out the battery and put in the AC adapter and try to start your laptop on AC adapter alone, if it starts that means either your battery or *********** board is bad, you can check if the battery is bad by replacing it with a new battery and if it works with new battery that means the old battery was bad but if it only works without battery with ac adapter and new battery also didn't work, that means motherboard is bad, Call dell tech support

If you think the info given by me was helpfull please do rate me
Regards
Ltoso

Ac adapter does not connect to battery


You either have a faulty ac adapter; a bad power supply in your laptop; a bad battery; or a blown LED indicator light.
1. If the connection is not loose when you plug in your ac adapter try letting the laptop charge for a while. (If you are using the correct ac adapter)
2. Try removing your battery and using the ac adapter. If this works the battery is bad.
3. Try a new ac adapter.
4. Power supply is bad

It could be one of three things. It could be a bad battery, a bad ac adapter, or the recharging circuitry could be bad. I would try pulling the battery out, and see if the laptop will startup and run strictly off of the ac adapter. If that does not work, you have a bad ac adapter. If that works, and the battery has any charge left, try running it strictly on the battery. If it doesnt work, you have a bad battery. If it does work, the circuitry is bad and you will probably need new motherboard. One other thing you can check is where the ac adapter and battery plug into the laptop, and make sure there is no corrosion that could be causing a short.

Sony Vaio ac adapter submerged


If the ac adapter was plugged into the laptop at the time may be bad news. Unplug AC adapter, take out the battery and hold power button for 10 seconds. Then connect AC adapter and hit power. If that doesn't work put battery back in without ac adapter and hit power button.

If neither test works bring to repair center for diagnosis. Best case AC adapter would need replacing. Worst case Motherboard fried.

Thanks
